我正在尝试使用以下功能在购物车中更改产品价格：
add_action( 'woocommerce_before_shipping_calculator','add_custom_price'
);
function add_custom_price( $cart_object ) {
foreach ( $cart_object->cart_contents as $key => $value ) {
$value['data']->price = 400;
}
}
它在WooCommerce版本2.6.x中正常工作,但在3.0版本中不再起作用
如何在WooCommerce 3.0版中使其工作？
谢谢.

使用WooCommerce 3.0版,您需要：
>改为使用woocommerce_before_calculate_totals钩子.
>改用WC_Cart get_cart()方法
>改用WC_product set_price()方法
这是代码：
add_action( 'woocommerce_before_calculate_totals','add_custom_price',20,1);
function add_custom_price( $cart_obj ) {
// This is necessary for WC 3.0+
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Avoiding hook repetition (when using price calculations for example)
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// Loop through cart items
foreach ( $cart_obj->get_cart() as $cart_item ) {
$cart_item['data']->set_price( 40 );
}
}
代码在您的活动子主题(或主题)的function.PHP文件中或在任何插件文件中.
此代码经过测试并可以使用.
Note: you can increase the hook priority from
20to1000(or even2000) when using some few specific plugins or others customizations.
